Description

Explosive charging structure for blast hole Technical Field The application relates to the technical field of blasting, in particular to a blasting hole charging structure. Background When carrying out blasting operation, a plurality of explosives probably need to be put into in the single big gun hole, if do not do any processing, directly throw into the blast hole with the explosive, can lead to the explosive to pile up, influence the blasting effect, for scientific and reasonable blasting operation, need control the interval of explosive, make the explosive explosion produce the effect of anticipation. Disclosure of utility model Accordingly, it is an object of the present application to provide a blasthole charge arrangement for controlling the spacing of explosives. The technical scheme of the application is as follows: the application provides a blast hole charging structure which comprises a connecting rod fixedly connected between end covers, wherein an accommodating space is enclosed by the connecting rod, a partition plate is arranged on the connecting rod in a penetrating way, a fixed sleeve is screwed on the partition plate, a movable sleeve is screwed on the connecting rod, and the movable sleeve is in rotary connection with the fixed sleeve. By adopting the technical scheme of the application, the partition board can be driven to move along the connecting rod by rotating the movable sleeve, so that the interval between the explosives in two adjacent accommodating spaces can be conveniently controlled. In some implementations, the connecting rod is disposed parallel to the axis of the end cap. In some implementations, the connecting rods are evenly distributed along the circumference of the end cap. In some implementations, the connecting rods on both sides of the end cover are screwed with positioning sleeves. In some implementations, smooth holes are provided in the separator for the tie rods to pass through. In some implementations, an outside of one of the smooth bores is provided with a ring groove for screwing the retaining sleeve. In some implementations, the ring groove is arranged coaxially with the smooth bore. In some implementations, a first card edge is provided on the fixed sleeve, a second card edge is provided on the movable sleeve, and the second card edge is in abutment with the first card edge. In some implementations, the first card edge is disposed coaxially with the retaining sleeve. In some implementations, the second card edge is disposed coaxially with the movable sleeve.
